Winds and wind systems on the Earth. 1  Wind is formed by the flow of air in horizontal directions. In meteorological definitions the coming direction of the wind is called wind direction. 2  1 m/s = 3.60 km/hr = 2.24 mph = 1.94 knot.
The production of proteins involves two major steps: transcription and translation. Together, transcription and translation are known as gene expression. The process of transcription only involves two molecules: DNA and RNA. A DNA strand provides a template for the synthesis of a complementary RNA strand. This process is used to synthesize any type of RNA from a DNA template. Transcription of a gene produces a messenger RNA (mRNA) molecule.
Molecules involved in translation. Translation is a process where genetic information is translated from a ``nucleic acid language to an amino acid language. Translation is catalyzed by a large enzyme called a ribosome, which contains proteins and ribosomal RNA (rRNA). Translation also involves specific RNA molecules called transfer RNA (t-RNA) which can bind to three basepair codons on a messenger RNA (mRNA) and also carry the appropriate amino acid encoded by the codon. The ribosome assembles on the first AUG (start codon) in the mRNA.
